ADJUSTABLE SUPPORT FOR BURNER-PLATES.

Specification of Letters Patent.

Application filed February 24, 1913.

Patented Oct. 27, 1914. Serial No. 750,211.

To all whom it may concern Be it known that I, JULIUS H. BECKER, acitizen of the United States, residing in the city and county of SanFrancisco and State of California, have invented new and usefulImprovements in Adjustable Supports for Burner-Plates, of which thefollowing is a specification.

This invention relates to an adjustable burner plate for liquidhydrocarbon fuels.

The object of this, invention is to provide a simple and durableadjustable burner plate of the type used in down-draft furnaces usingliquid hydrocarbon fuels.

The invention consists of the parts and the construction and combinationof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings, 1n Which Figure 1 is a verticalsection of a clowndraft furnace showing the application of the burnerplate. Fig. 2 is a plan section.

Referring to the drawings, A indicates a base plate suitably mounted orsecured in the base portion of a downdraft furnace, generally indicatedat B. Centrally formed or otherwise secured upon this plate is a hollowsocket member 2, provided wit-h a central opening 3 formed for thepurpose of providing a communicatingpassage between the main combustionchamber 4 and an auxiliary combustion chamber 5.

Loosely mounted upon the socket member is a second socket member 6,which is connected by flanges 7 with a bracket plate 8 provided for thepurpose of supporting the main burner plate, indicated at 9. The bracketplate 8, together with the main supporting plate A, may be made of castiron or like material, while the burner plate 9 should preferably bemade of cast steel or like material which will be able to stand the hightemperatures of the furnace without cracking or bending out of shape.This is of great importance when one considers that any slight bendingor warping of the plate might cause an uneven flow or discharge of theliquid fuel from the plate with a consequent inequality of flamedistribution.

In operation, a temporary fire is made from any suitable fuel placed inthe auxiliary combustion chamber 5 below the burner plate 9, all draftopenings except the door 10 being closed. This fire is continued untilthe plate 9 becomes sufficiently heated to vaporize water and oildelivered to the plate. Oil and water in the right proportions are thengradually turned on and are ignlted by the flames discharging around theedge of the plate 9 from the lower auxiliary combustion chamber 5. Theribs or flanges 7, connecting the bracket plate 8 with the socket member6, are so positioned as to form passages 11 through which the flamesfrom the auxiliary combustion chamber may discharge.

The moment suflicient heat has been generated within the main combustionchamber to support combustion, the fire within the temporary orauxiliary heating chamber 5 may be drawn and the door 10 closed. Themain draft necessary for combustion is then admitted, together with thefalling fuel mixture, through a central opening 12. The fall of themixed oil and water from the conveying pipe 12 is sufficient to cause itto spatter and atomize. The mixture is thus evenly spread over the plateand burns with a flame which spreads to all sides of the combustionchamber.

From the above description it can easily be seen that the adjustablemounting of the burner plate 9, with relation to the main supportingbase A, is of great importance. Any settling of the brick work of thefurnace would otherwise disturb the level of the plate and cause anuneven flow of fuel from the plate with a consequent poor distributionof fuel from the plate.

The plate mounting here shown is simple and substantial in constructionand may be easily adjusted at any time without shutting down the furnaceor disturbing the fire in any way, as the plate may be easily adjustedat any time through the central opening 12 by the aid of a rod orsimilar means by which the plate may be slightly tapped to adjust itslevel. The oil discharged from the plate acting as a level willimmediately indicate the amount of adjustment necessary. The burnerplate being mostly subjected to the high temperatures of the combustionchamber may be renewed and re placed at any time without disturbing theadjustable mounting on which it is supported.

The materials and finish of the several parts of the device are such asexperience and judgment of the manufacturer maydictate.

I wish it understood that various changes in form and proportions ofconstruction may be resorted to within the scope of the appended claimsand that I do not Wish to limit myself to the specific design hereshown.

Having thus described my invention, what I claim and desire to secure byLetters Patent is To 1. An adjustable support for burner plates"comprising in combination, a base plate, a

hollow socket member having a central opening, formed on said plate, anadjustable support mounted on the socket member, and 1.5 a burner platecarried by said support.

2. An adj ustable support for burner plates comprising in combination, abase plate, a hollow socket member v having a central opening formed onsaid plate, a second socket member having a series of radially 20extending arms upon which is secured an open bracket plate and mountedon said first-named socket member, and a burner plate carried by saidopen bracket plate.

In testimony whereof I have hereunto set 5 my hand in the presence oftwo subscribing witnesses.
